CVE-2023-29215 : What You Need to Know

Apache Linkis <=1.3.1 is impacted by a deserialization vulnerability that can lead to remote code execution when malicious Mysql JDBC parameters are configured. This CVE was published on April 10, 2023, by apache.

Understanding CVE-2023-29215

Apache Linkis version 1.3.1 and below are susceptible to a deserialization vulnerability that enables remote attackers to execute arbitrary code through JDBC EngineConn Module.

What is CVE-2023-29215?

CVE-2023-29215 is a deserialization vulnerability in Apache Linkis that allows threat actors to trigger remote code execution by exploiting the lack of parameter filtering in Mysql JDBC configurations.

The Impact of CVE-2023-29215

The vulnerability in Apache Linkis <=1.3.1 can have severe consequences, including unauthorized remote code execution, leading to potential data breaches and system compromise.

Technical Details of CVE-2023-29215

The vulnerability description highlights the issue of ineffective filtering of parameters, exposing systems to malicious Mysql JDBC configurations in the JDBC EngineConn Module.

Vulnerability Description

In Apache Linkis <=1.3.1, the lack of parameter filtering allows attackers to exploit the Mysql JDBC URL, leading to deserialization vulnerabilities and remote code execution.

Affected Systems and Versions

Apache Linkis versions up to 1.3.1 are affected by this vulnerability, while users on <=1.3.0 are particularly at risk.

Exploitation Mechanism

Attackers can exploit this vulnerability by manipulating Mysql JDBC parameters, triggering deserialization flaws that pave the way for remote code execution.

Mitigation and Prevention

To safeguard systems from CVE-2023-29215, immediate actions and long-term security practices are crucial.

Immediate Steps to Take

Users are strongly advised to upgrade Apache Linkis to version 1.3.2 to mitigate the risk of deserialization vulnerabilities and prevent remote code execution.

Long-Term Security Practices

Implement robust parameter filtering mechanisms and regularly update software to address potential security loopholes.

Patching and Updates

Stay informed about security advisories and promptly apply patches released by Apache to ensure the protection of systems.
